Re: Preen Weed Preventer - flower beds- chickens in reply to George Marsh, 02-26-2013 09:56:37. Most real Preen has Treflan in it. If you follow the label directions it is safe for your water supply. Clay should tie it up.
Preen isn't a weed killer per se -- it's a pre-emergent which means it prevents weed seeds from germinating. It won't do anything for the weeds that are currently in your beds. I have on and off used Preen in my gardens.es, as Dorothy said, Preen is not a weed-killer, it's a pre-emergent and its effect lasts for about 3 months, not more. Whatever weeds are already in a soil they will grow thru it, but it will prevent FRESH seeds from germinating.
